Rear Rad replacement

2016 winnebago forza 34t. Freightliner XCS Chassis. We had to replace the rear Radiator on our Forza while traveling. Matheny Freightliner shop In Mineral Wells WV did the repair work. $4100 in parts and labor. 3 days in the shop. Very good service to get me in and fixed in a timely manner. They actually had 30 new radiator in their system. Freightliner says rear rad corroded in bottom corners and gave out. We were ready to head over the mountains when i discovered the leak at the CG before heading out. My question has anybody had any luck with Freightliner or Winnebago with help on cost. Say a refund of sorts. New radiator after 6 years sure seams odd. Seems like Freightliner would be my first call.

I'm shocked every time I hear about these $5000 radiators leaking.

A cheap car radiator can last 20 years, no issues...

I doubt freigtliner will help though.

Seems like the key is to blow out any debris that forms in the corners of the radiator.

On my freightliner chassis there are bracket supports in the corners. The passenger lower one is AWLAYS clogged with dirt, touching the radiators. Likely encourages rust...

Blow out that area often with air, may help...

Radiator replacement

We are considering a radiator replacement and wondered if they had to take the back off the coach to get to the radiator to replace. We have hail damage to the fins area..hubs wants it replaced.
Hope you are still traveling down the road.
Cheers!

Doesn't hurt to try, but good luck. Out of warranty is out of warranty.

I've found lots of debris (leaves, acorns, dirt) collects in the bottom of the fan shroud against the radiator. So I drilled two holes, one in each corner of the shroud to allow water/debris to more easily escape.

Wow,
Things must have really changed in the last ten years. Long story short. We purchased our coach, an '04 Itasca Horizon 36GD with the CAT C-7 330HP over 10 years ago. Shortly after we purchased it, around 6 months or so, it developed a radiator leak. And yep, the leak was at a lower left corner. I did the work of yanking that CAC and radiator out and needless to say, it was quite a learning curve and job to get that system apart. The radiator, with only about 6-7 years on it, was shot and needed replacement. I'd looked it up on what was called then, *Access Freightliner* and the direct replacement for my coach was at that time, $1,750 and was gonna take weeks to get.

A local radiator shop that was looking at my radiator advised: "you don't want one of those, let me see what we can get you". About 2.5 minutes on his computer revealed a copper-brass replacement for my aluminum-plastic version and, he could have it in ONE DAY. The best part, $1,200 vs the $1,750 from Freightliner. And it arrived the next day as promised.

It's been in there now for several years and my temps are the exact same as the aluminum version that was in there. So much for the theory of "Aluminum radiators cool better". We now have 103,000 miles on this coach and it's running every bit as good as it did when we purchased it, 10+ years ago. Anyway, as stated, things must have really changed in the fact that these same style/size radiators are now upwards of $5,000 or more.
